| 摘 要： | 通过粉末XRD测定了CdGd2(WO2)4单晶的晶格常数，由σ- T和ESR实验得出晶体具有顺磁性，但又具有磁各向异性，探讨了晶体的磁各向异性与晶体结构的关系，计算了各向异性g2张量，所得结果和实验符合甚好.

| Abstract: | The structure and magnetic properties of CdGd2(WO2)4 single crystal were studied by X-ray diffraction, magnetic measurement and electron spin resonance (ESR) experiments. The results showed that the crystal structure is tetragonal with lattice parameters a=b=0.5204 nm and c=1.136 0 nm. σ- T and ESR experiments showed that the crystal is paramagnetic and anisotropic. The magnetic properties of the crystal reflected its structure characteristics well. Landé factor g2 tensor was calculated, and found to be consistent with the result obtained by theoretical calculation. |
